Decent Cooler ( ARCTIC Freezer 7 Pro Rev 2 )
on February 16, 2017
I have an Intel Xeon w3690 with 6 cores and 12 threads @ 3.46 GHz, that runs very hot. With my previous cooler I got idle temps of the mid 40's and under 100% load I got temps of 70-71 which is fine. As you can see in the picture my previous cooler (on the right) compared to the ARCTIC Freezer (on the left), they both have a nearly identical number of pipes and fins on the heatsink, and nearly identical fan size although the ARCTIC is a bit bigger. Temps are almost the same, in fact the ARCTIC cooler temps are roughly 10 C higher at idle and full load respectively, BUT, the ARCTIC cooler is quieter. Although the cooling is a bit worse, the noise compared to my previous cooler is a huge difference but only at idle. When playing games or doing anything else that uses a lot of my CPU the fan is deafening with either cooler. Currently as I am typing this I am running a Prime95 torture test to put my CPU under 100% load on all the cores, and the fan is about the same at 100% RPM in the noise department. I did use the pre-applied thermal compound that came with the heatsink vs. Arctic Silver Ceramique on the previous cooler which is a superior compound. I will try some of the ceramique for a few days and see if the temps are any better, and if not I will revert to my old cooler. All in all, not too impressed with either the sound or the cooling efficiency. You may have a different experience than I using a consumer chip with a much lower TDP and heat production than my server chip. If I am able to get better temps with a better thermal compound I will raise the score by 1 because the sound at full RPM is pretty loud and I was expecting it to be much quieter than it is, as that is one of the selling points which I based my purchase decision on.
Edit: Well I figured out the problem, even trying different thermal pastes the temps were still way higher than my previous cooler, was playing some Fallout 4 and with just 60% cpu usage the cores were getting into temps of the high 80's. Turns out the copper plate under the heatsink is not big enough, and doesn't cover the entire CPU lid, which is where the high temps were coming from. I guess my xeon is too big for it, or perhaps my mounting hardware was faulty, I'm not sure. All I know is this didn't work well for me.
